I have 4 sets of Red anodized Small Valve covers, manufactured by Seacraft, $30.00 per set.They fit perfect on Saito's , 72, 82,91, 125, and 182TD Twins.. They will not fit the Saito 120, that is a larger engine, on a 150 frame.No need for extra valve gaskets, use the existing ones that are on the engine. These covers in my opinion give greater cooling effect on the to end because of the milling of slits as evident in the photos. The really do give the engine a complete new look.
